DSM Guestbook only shows for admin - not showing to public (3 posts)

I just installed DSM Guestbook and it looked great while I was logged in as admin viewing the site, but when logged out the public cannot see the guestbook nor can they see the widget. I found some instructions to set define('ROLE', "0"); but it still does not show in public view. I'm not good with PHP so could really use some support here. LIke I said, it is perfect when I'm logged in as admin.
